Features h Rated capacity: 100 kN (10,000 kgf, 22,500 lbf) h Quick set-up with rapid clamping and unclamping action h Easy specimen loading for increased productivity h Self-tightening wedge design eliminates slippage h Interchangeable jaw faces for a range of specimen geometries and types h Fixed faces and moving body during specimen loading h Temperature range: -73 C to +250 C (-100 F to +480 F) Description The manual wedge action grip is designed for easy specimen loading, alignment and positioning. After initial face to specimen contact, gripping force will increase as the testing load increases. Virtually no pre-load is seen during specimen clamping due to Instron's design of moving grip bodies. This makes them particularly suitable for testing high strength materials, such as metals and composites, ensuring that specimen slippage is eliminated. Principle of Operation The wedge action principle of these grips allows them to be tightened onto a specimen without altering the vertical position of the faces in relation to the specimen. This is accomplished by a design, which moves the grip body to close the faces. This feature makes it possible to preselect the exact point at which the specimen will be held with consistent gage length and no compressive force applied which may cause specimen buckling. A strong clamping force can be applied to materials that are difficult to hold through a high mechanical advantage achieved by the tightening mechanism. The grip faces are spring loaded against a shoe which is in a fixed position in respect to the testing frame holding mechanism, only a light initial gripping force needs to be applied to the specimen. As the grip is tightened, it's frame is drawn up and the inclined sides push against the matching side of the faces which move laterally against the specimen. A shoe incorporated to the driving shaft prevents the faces from moving. The open front design of the grip frames allows faces to be easily interchanged as well as easy specimen loading. Because the faces are held in a fixed position, there is no recoil, or loosening, when the specimen ruptures and if an extensometer is attached, it will remain in place. Application Range h Type of loading: Tension. Not suitable for through-zero/reverse stress or fatigue testing h Specimen material: Wires, plastics, metals, elastomers. h Specimen shapes: Flat, round. 2716 Series Manual Wedge Action Grips Catalog Number 2716-003 2716-003 wedge action grips d Faces: Round threaded, V-serrated, and flat serrated (1.5 mm) d Corporate Headquarters 100 Royall Street, Canton, Massachusetts 02021-1089, USA Tel: +1 800 564 8378 or +1 781 575 5000 Fax: +1 781 575 5751 Instron Industrial Products 900 Liberty Street, Grove City, PA 16127-9969, USA Tel: +1 724 458 9610 Fax: +1 724 478 9614 2716 Series Manual Wedge Action Grips Catalog Number 2716-003 Instron is a registered trademark of Instron Corporation.
